2000 buick park avenue ulta passenger side only blows hot air.. drivers side air works great
the heat for driver, passenger and back seat works fine.
The cold air conditioning works fine for driver and back seat.
The passenger cold air only blows hot air.. the passenger climate control
has no effect on heat/cold.. .
any ideas on whether it is the passenger climate control or a duct that isn't
shutting, and how would one test this.
